(from Gourmet Popcorn by Georganne Bell, via bakeat350.net)
10-12 cups popped popcorn (here's how I pop mine)
1/2 cup unsalted butter, melted
2/3 cups light brown sugar
1/3 cup flour (toasting optional)
1/4 teaspoon kosher salt
1 teaspoon vanilla
1/2 cup mini chocolate chips
Place the popcorn in a large bowl with a rimmed cookie sheet underneath. In another bowl, whisk the melted butter, brown sugar, flour, salt, and vanilla together. Pour over the popcorn, stirring to coat as you pour. Toss to distribute evenly.
Add the chocolate chips and toss again. Serve immediately, or store in an airtight container for up to a week.
